This invention pertainsto a multiple light such-fais a onibination taillight and spotlight or combination tail' light,` spotlightand backi''glight. l l `V The particular feature Vofthe invention resides in theconstruction of the lainp,-V and prticiilarly the Contact inember forprovid'fv ing separate and distinct contacts betweentheconnct'ir'lgyplug and several lamps. y

Heretofore it has been the4 practice in such sti'utiirs to employconnecting plugs slid-` ably mounted with the usu'albayonet slot conI``nectioi' having af'pir Vof spring pressed Contact pins foi* yieldinglymaking contact with the landps; "saidl @plugs coiitaining v spiralsprings andsuitable tubes or sleevesin whichv tlie` pins are slidablyAinoiintetl, `This type of. spring ciitact has been found to'be unfit byieason of the Sliding" pins sticking or becoming rusted or the springslosing their resiliency by "reason of exposure to the weather,

The principal object of this invention is to provide a ebiitact mein-berwhich may be used in connection` with a plug having rigid contactsthereon so as not to be dependentY upon the usual sliding spring pressedcontact pins mounted in the plugs. y

The `full nature of the invention will be understood from theaccompanying drawings'- and the following description and claims.

Fig. 1 is a central vertical section through i a combination stop kandtail light. Fig. 2 is a. section taken on the line 2-2 thereof. Fig. `3is a sectional view taken on vline 3 3 of Fig; 1 and'in the directionl`ofthe arrows. Fig. 4 is a central section through a modified insulationContact illustrating an additional spring Contact. Fig. 5 is the samepasFig. 2 showing a modified form having three con-` tacts in place of two.

In the drawings there is shown a combination tail and stoplight havinga` casing l() `supported on a vehicle by the screws 12.

y Mounted in the casing there is a reflector 14 Vfor the stop light bulb1'5, the same being posi.-

tioned within an' upper compartment which is separated from the lowercompartmentV by` thepartition plate 16. 'The lowercompart'-ments-comprises a downwardly extending tongue 17 in which a, tail lamp18 is mounted.
